The rotation and slip of part 230.Because the 3rd lens subassembly 230 is the lens group that is exited from reference optical axis OA during not photographing
Part, therefore following for explanation is easy to, the 3rd lens subassembly 230 is referred to as exiting lens subassembly 230.
With reference to Fig. 7, α represents Y-Z plane, and β is represented parallel to plane α and spaced apart in the-x direction with plane α
Another plane of Δ X.As shown in fig. 7, reference optical axis OA is arranged on plane α along the Y direction, and during not photographing, the 3rd group
The optical axis OA3 of lens L3 is arranged on plane β.Now, because plane α and plane β are parallel to each other, so reference optical axis OA and
The optical axis OA3 of three lens cluster L3 mutually disjoints during not photographing.Additionally, as shown in fig. 7, during not photographing, reference light
The optical axis OA3 of axle OA and three lens cluster L3 is not parallel each other.As described above, during not photographing, three lens cluster L3's
Optical axis OA3 and reference optical axis OA is not parallel each other and mutually disjoints.Briefly, during not photographing, three lens cluster
The optical axis OA3 of L3 is disposed in the so-called " deflection on reference optical axis OA（skew）Position（That is, optical axis OA3 and reference optical axis OA
Locus that is neither parallel to each other nor intersecting each other）”.
If when the pattern of lens barrel 3 changed into not photograph mode from photograph mode, the 3rd lens subassembly（Exit
Mirror assembly）230 rotations are then appreciated that three lens cluster L3 has during not photographing and are located in α planes without sliding
Optical axis OA3 '.Because such optical axis OA3 ' intersects with reference optical axis OA, therefore it is not in the deflection position on reference optical axis OA
Put.
The 3rd lens subassembly is performed while changing into not photograph mode from photograph mode due to the pattern in lens barrel 3
（Exit lens subassembly）230 exiting on reference optical axis OA, as shown in figure 5, so exiting lens subassembly 230 during photographing
Residing space is used as the receiving space of the other lenses component during not photographing.Therefore, with exit not performing
The thickness of lens barrel 3 is compared in the case of the exiting of mirror assembly 230, and thickness of the lens barrel 3 during not photographing can subtract
It is small.
Because the operation of exiting for exiting lens subassembly 230 not only includes the rotation around rotary shaft AR but also is included in rotary shaft
Slip on the direction of AR, it is possible to the thickness for increasing lens barrel 3 reduces effect.Thickness as described above reduces effect
To be described in more detail with reference to Fig. 8 to Figure 10.
Fig. 8 is to show to exit lens subassembly 230 along the length H1 of the center line of the 3rd lens subassembly 230 and exit lens
Component 230 is in the view with the centreline space length of the position of Δ X separated by a distance.Fig. 9 is to show with rotation process and slip
Operation is performed to be exited in the case of the exiting of lens subassembly 230 in the sectional view for exiting the structure near lens subassembly 230, Figure 10
For show only performed with rotation process exit the exiting of lens subassembly 230 in the case of exiting near lens subassembly 230
The sectional view of structure.
With reference to Fig. 8 to Figure 10, along the line A-A for exiting lens subassembly 230（Center line）The length in the section of interception is H1,
Along the section that line B-B is intercepted（Section B-B）Length be H2, its center line B-B and the center line A-A for exiting lens subassembly 230
Δ X spaced apart.Such as knowable to accompanying drawing, H2 is shorter than H1.
As shown in figure 9, exiting the exiting including rotation process and slide of lens subassembly 230 in such as present embodiment
In the case of, in not camera positions, exit the free end portion 250a of the lens installation component 250 of lens subassembly 230（Distal portion
Point）The upper part 211a with the lens installation component 211 of the first lens subassembly 210 is not contacted.In other words, even if first is saturating
Mirror assembly 210 is inside（In the Y direction）Be moved to degree as shown in Figure 9, exit lens subassembly 230 still not with the first lens
Component 210 is mutually disturbed.
However, present embodiment is different from, if exiting exiting for lens subassembly 230 only includes rotation process, such as Figure 10
It is shown, in not camera positions, exit the free end portion 250a of lens subassembly 230 and the upper part of the first lens subassembly 210
211a is contacted.In other words, if the first lens subassembly 210 is inside（In the Y direction）It is moved to degree as shown in Figure 10（Its etc.
In degree as shown in Figure 9）, then exit lens subassembly 230 and mutually disturbed with the first lens subassembly 210.If because exited
Exiting for lens subassembly 230 only includes rotation process, then the length of the section B-B arranged on Y-Z plane becomes big distance, delta H
（=H1-H2）Degree.In order to avoid this interference, the distance backward of the first lens subassembly 210 should subtract during not photographing
Small, in the case, compared with the situation according to present embodiment, the thickness of lens barrel 3 reduces effect during not photographing
Can reduce.
In order to performed when pattern changes into not photograph mode from photograph mode exit lens subassembly 230 exit operation,
Lens barrel 3 includes exiting unit.Exiting unit includes rotary unit 310（In Fig. 9）With slip driver element 350, rotation list
